But they have other costs like admin costs, that us, engineers, rarely think about. You counted the guy behind the machin, but you have to add the whole team that works around him.

You can be the best enginer designing an almost perfect product, if it does not fit any market, or if no one knows it even exists, it is worth nothing.
And I am saying that being a design engineer. We are only a part of a chain.

I guess the 50% margin is based on umcompressible costs (admin, marketing, research, advertizing ...) that any business has to handle.
